Lula wins Brazil's presidential runoff with 50.9% against prediction markets' odds

Luiz Inácio Lula da Silva won Brazil’s presidential runoff on Sunday, beating Flávio Bolsonaro despite odds that gave him roughly a one‑in‑five chance of victory on major prediction markets. The 77‑year‑old former president secured about 50.9 % of the vote, ending a tightly contested race that kept the nation on edge through the night.

The surprise stems from a confluence of factors that made Lula an underdog in the eyes of traders. His 2022 comeback was marred by a fragmented left, a fragmented right, and lingering corruption scandals. Meanwhile, Flávio Bolsonaro, son of the former president, rode a wave of anti‑establishment sentiment and promised a hard‑line approach to crime and the economy. At noon EDT on the day of the vote, Kalshi listed Lula’s odds at 20.2 % and Polymarket at 20.5 %, reflecting market doubts about his ability to rally the centre‑left and win over swing voters.

Analysts say the result shows the limits of betting markets in volatile political environments. Turnout was higher than expected, especially in the northeast, where Lula’s social programmes still enjoy strong support. His victory also signals a shift back toward more progressive policies on Amazon protection, minimum‑wage hikes and social spending. International investors responded with a modest rally in the Brazilian real, while critics warn that Lula will need a broad coalition in Congress to pass reforms.

Lula is set to be inaugurated on 1 January 2027, and his first task will be assembling a governing alliance among a fragmented parliament. He has pledged to prioritize climate action, economic stability and a crackdown on corruption. The new administration will face a tight fiscal outlook and a divided opposition led by the Bolsonaro family. How quickly Lula can translate his electoral win into legislative success will shape Brazil’s trajectory for years to come.
